I have disassembled it and found the error. The central zoom lens element has loosened form the barrel cam. Tree spring loaded sprigs has obviously lost their grip in the barrel cam when it was dropped. I have not disassembled more of the lens than I am able to reassemble again. But I cannot find a way to get the tree sprigs into the barrel again without disassemble it further. So far I have removed the lens mount, the PCB and the barrel with the rear lens. I want to get into the front of the lens, but cannot figure out how to get in there. Can anybody help me with a hint or a drawing of the lens?   Per Rating: N/A Votes: 0 (Vote!)

For the record I will short describe the disassembly of the front. The AF/M switch has to be removed. The manual focus ring can be separated into two rings. 3 screws holding the front cover shows up. From here the rest is rather obvious. The lens is now reassembled and it seems to be working.
